Specification of Letters Patent.

Patented Apr. 29, 1919.

Application filed May 8, 1917 a Serial No. 167,379.

T0 at whom it may concern Be it known that I, PINCUS FARE, a citizen ofthe United States, and a resident of the city of Newark, county ofEssex, and

State of New Jersey, have inventeol a certain new and useful Improvementin Motors, of which the following is a specification.

My invention relates to spring motors, and more particularly to motorsfor use in talking machines, and has for its object to produce a springmotor, the motion of which will be automatically arrested when thespring is being rewound.

This and further objects will more fully appear in the followingspecification and accompanying drawings considered together orseparately.

I have illustrated one embodiment of my invention in the accompanyingdrawings, in which like parts are designated by similar referencecharacters, and in which,

Figure 1 is a side elevation of a talking machine motor provided with myinvention;

Fig. 2 is a front elevation of the same; and

Fig' 3 is a detail view of the lock actuating mechanism.

In the drawings, I have shown a long running talking machine motor, of awell known type. The motor comprises the usual frame 1, spring barrel 2,winding shaft 3, winding gearing 5, transmission or unwinding gearing 1,6, 7 and 7, governor 8, speed adjusting device 9, and turn-table shaft10, on which a turn-table (not shown) is removably supported. Thewinding of the springs is accomplished by the engagement of the pinion5, carried on the winding shaft 3, with a spur gear on the far end ofthe spring shaft. As the motor unwinds the spur 4 at the opposite end ofthe spring shaft rotates and by means of the gear train at that end ofthe motor drives a horizontal shaft which carries a bevel gear whichdrives a bevel pinion 7 on the turn-table shaft 10. The turn-table shaftcarries the usual worm wheel which engages and drives a worm on a shaftwhich rotates the governor 8.

The winding shaft 3 is provided with a ratchet 11 adapted to be engagedby a pawl 12 to prevent the shaft from rotating as the spring isunwound. Loosely carried on the winding shaft is a keeper 13 which ismounted between a spring washer 14 and a rigid washer 15. The keeper isrotatable with the shaft by reason of the frictional engagement of thewashers. The keeper is provided with a slot 16 with which engages a pin17 carried by the pawl 12. When the winding shaft is rotated in theclock-wise direction, the keeper by its frictional engagement, will tendto rotate with it. This movement will tend to disengage the pawl fromthe ratchet teeth and as long as the shaft turns in the clock-wisedirection, the pawl will be held away from the ratchet. When the abovedescribed movement of the shaft 3 ceases, the tendency of the shaft is 1to rotate in the other direction by the unwinding of the spring. Suchmovement of the shaft will immediately be communicated to the keeper 13,the pawl will be drawn into the path of the teeth of the ratchet and themovement arrested.

Pivoted at 18 on the frame 1 is a lever 19, one end of which carries afoot 19 which bears against the keeper 13. The opposite end of the leveris bent at right angles and carries an elongated brake shoe 20. Thebrake shoe 2O normally lies in a plane parallel to the governor shaftand in proximity to the periphery of the brake disk 21 carried on thegovernor shaft. A spring 22 holds the lever 19 normally in position, asabove described.

In operation, the first movement to turn the winding shaft in theclock-wise direction will raise the depending finger 23 of the keeper torelease the pawl. This same move ment will raise the end of the levercarrying the foot 19 against the tension of the spring 22 and apply thebrake shoe 20 to the disk 21 of the governor shaft and arrest therotation of the said shaft and stop the motor.

As soon as the winding shaft starts to rotate in the anti-clock-wisedirection, the keeper will be withdrawn from beneath the foot, thespring 22 will move the brake shoe from contact with the disk, and themotor will operate.

The brake shoe is elongated so that it may engage the disk irrespectiveof its position on the governor shaft caused by the speed of the motor.

While I have shown and described my invention as applied to a talkingmachine motor, I desire to have it understood that the invention is notlimited to such use, but may be applied to any form of spring motor.

I have shown lever operating means working in conjunction with thewinding shaft; it will be understood that it may be operated by anyother part of the apparatus which may be rotated during the windingoperation.

In accordance with the provisions of the patent statute, I havedescribed the principle of my invention together with the apparatuswhich I now consider to represent the best embodiment thereof, but Idesire it understood that my invention is not confined to the particularform of apparatus herein shown and described, and, therefore, I claimbroadly the right to employ all equivalent instrumentalities comingwithin the scope of the claims, and by means of which objects of myinvention are attained, and the new results accomplished, as herein setforth, as it is obvious that the particular embodiment herein shown anddescribed is only one of many that can be employed to attain theseobjects and accomplish these results.

Having now described my invention, what I claim and desire to secure byLetters Patent is 1. A spring actuated motor, having a shaft for windingthe spring, a pawl for preventing backward movement of the windingshaft, a member loosely carried on the shaft, means for frictionallyengaging the member with the shaft, a connection between the member andpawl whereby as the mem ber is rotated in unison with the shaft the pawlwill be released from engagement with the shaft, and means operated bythe member when the shaft is rotated to wind the spring, for preventingmovement of the motor.

2. A spring actuated motor, having a shaft for winding the spring, apawl for preventing backward movement of the winding shaft, a memberloosely carried on the shaft, means for frictionally engaging the memberwith the shaft, a connection between the member and pawl whereby as themember is rotated in unison with the shaft the pawl will be releasedfrom engagement with the shaft, and a lever cooperating with a rotaryelement of the motor, operated by the member when the shaft is rotatedto wind the spring, for preventing movement of the motor.

Copies of this patent may be 3. In a spring actuated motor, a shaft forwinding the spring, a member carried by the shaft and movable relativelythereto, means for clutching the member to the shaft whereby it willmove with the shaft, a lever operated by the member, and a brake shoecarried by the lever.

4. In a spring actuated motor, a shaft for winding the spring, agovernor actuated by the unwinding of the spring, a member carried bythe shaft and movable relatively thereto, means for clutching the memberto the shaft whereby it will move with the shaft, a lever operated bythe member, means carried by the lever for engaging the governor andarresting the unwinding of the spring.

5. In a spring actuated motor, a shaft for winding the spring, agovernor actuated by the unwinding of the spring, a member carried bythe shaft and movable relatively thereto, means for clutching the memberto the shaft whereby it will move with the shaft, a lever operated bythe member, and a brake shoe carried by the lever, adapted to engage thegovernor and arrest the unwinding of the spring.

6. In a spring actuated motor, a shaft for winding the spring, agovernor actuated by the unwinding of the spring, a member carried bythe shaft and movable relatively thereto, means for clutching the memberto the shaft whereby it will move with the shaft, a lever operated bythe member, a brake shoe carried by the lever, adapted to engage thegovernor and arrest the unwinding of the spring, and means fordisengaging the brake shoe from the governor.

7. In a talking machine, a spring actuated motor, a shaft for windingthe spring, means whereby the unwinding of the spring will rotate theturn-table spindle of the motor, and means actuated by the winding shaftfor automatically arresting the revolution of the turn-table spindleduring the rewinding of the spring.
